Abstract
Rich Internet Applications (RIAs) in general and Single Page Applications(SPAs) in particular have revolutionized the last decade of computing by moving
the locus of computing from the server to the web browser. This foundational shift
changes how users perceive and interact with web-based applications. Correspond-
ingly, it fundamentally alters how software application development and testing
must occur.
In this research, we proposed an adaptation of an existing testing strategy
called User Session Based Testing (USBT) which uses capturing and replaying user
sessions, to the new RIA operating model. This technique, most often applied dur-
ing regression or beta testing, uses existing applications and end-users to rapidly
construct test suites. This adaptation uses client-side instrumentation to capture
behavior and responses in a novel manner, using Domain Object Model (DOM)
Mutation Observers and HTML5 Canvas instrumentation. We conducted a trial
on eight RIA applications (video games) using this adapted technique in order to
capture and analyze application responses to user behavior. We intended to under-
stand if these event traces could form an effective test suite. We studied the DOM
API to select common element attributes that they then captured. Using a testing
technique called Mutation Testing, we attempted to determine the effectiveness of
the test suite when applied to mutants of the original applications. The mutants
contains systematically seeded faults. We also constructed several custom-designed
oracle comparators to determine if these event traces could detect injected faults.
As a result, we showed that USBT for RIAs could be an effective technique.
